/ENABLE[=NAME=(name[,...])]

    Enables one or more ACME agents in the specified order. Ordering
    of ACME agents is significant, as the ACME_SERVER processes user
    authentication requests in the order specified. The name variable
    is a case-insensitive string argument.

    If you do not specify the NAME keyword, the same list of
    ACME agents will be enabled that were enabled by a previous
    /ENABLE command. If no previous /ENABLE command was issued, all
    configured ACME agents are enabled.
